Dr. Rossmo, a criminologist and a police officer has formulated a procedure that has been titled “geographic profiling” which is explained and illustrated in this relatively easy-to-follow book. A seasoned specialist in law enforcement, Dr. Rossmo has combined his experiences as a police officer with his education in criminology to offer an interesting formula intended to facilitate the process of investigating particularly serial crimes. The book's 12 chapters are enhanced by a glossary and lengthy bibliography. Criminal behavioral demography occupies nine of the chapters with one devoted to “geographic profiling,” another to applications and a final concluding chapter. The reader will find a preponderance of descriptive criminology and an relative absence of criminal psycho dynamics. This is not a work focusing on causality or etiology of criminal behavior. Rather, the author utilizes characteristics similar to diagnostic symptoms, a procedure that lends itself to the formula proposed by Dr. Rossmo. At the center of his model is computer analysis of variables associated with crime scene locations ideally resulting in the identification and apprehension of the perpetrator.
